oepals 5. Petals 5, valvate. Torus thick. Stamens 10 ; filaments subu- 

 late, glabrous. Ovary of 5 nearly distinct carpels, eacli witli a glandular 

 terminal appendage. Styles inserted below the middle, and immediately 

 united into one filiform style, with a small stigma ,• ovules 2 in each carpel, 

 supei-posed. Fruit-carpels 5 or fewer, often solitary by abortion, indehiscent, 

 expanded all round into a membranous wing, forming obovate or oval-oblong 

 samarae, the centre almost drupaceous, with a cartilaginous endocarp. Seeds 

 usually solitary ; testa thick ; albumen not copious ; embryo straight, with 

 ovate cotyledons. — Tree. Leaves alternate, pinnate, Flowers numerous, 

 small, paniculate.
